Sorry, forgot the link. This is the 2 hp compressor I was looking at:

I've just had a nasty thought about it though. The seller says it has a
2850 rpm 2 hp motor. Is there any chance a 1 hp 1425 rpm motor could
have been replaced with a 2850 rpm 2 hp motor to increase the output?
I've never seen a compressor with a 2850 rpm motor before. Apparently
this machine is 2 cylinder and each cylinder is 2" bore by 2" stroke.
Also the receiver looks a little rusty, but the machine is cheap. Might
want to get a hydro test on it?

Thinking about it again this morning I reckon I'll pass on this one too.
It looks just a bit too dodgy, even for me!
